Scientists map genome of domestic pig

SCIENTISTS have mapped the genome of the domestic pig in a project that could enhance the animal's use in the testing of drugs for human disease.

A study, published in Nature, identified genes that could be linked with illnesses suffered by farmed pigs, providing a tool for selective breeding to increase disease resistance.

"This new analysis helps us understand the genetic mechanisms that enable high-quality pork production, feed efficiency and resistance to disease," said Sonny Ramaswany, director of the US Department of Agriculture's National Institute of Food and Agriculture.

"This knowledge can ultimately help producers breed high-quality swine, lower production costs and improve sustainability."

Alan Archibald at the University of Edinburgh's Roslin Institute in Scotland, who worked on the project with collaborators in the Netherlands and the US, said it was the first good draft.

Archibald said the benefits of genome sequencing flow through more quickly in agriculture than human medicine "because we can use selective breeding."
